发光多孔硅材料的研究作为21世纪的关键新技术而受到重视,因为可用便宜而且工艺成熟的硅材料制备发光器件,实现全硅光电子集成.由于硅是当今应用最广泛的半导体材料之一,尤其是在大规模集成电路中的应用,如果能实现多孔硅发光的应用,将给光电子行业带来难以估量的影响,现在多孔硅已实现了红、绿、蓝光的发射,电致发光也已实现,使多孔硅向实用化迈出了一大步. The study of luminescent porous silicon material has gained considerable attention as a key new technology in the 21st century because of its ability to produce light-emitting devices using inexpensive and well-established silicon materials for all-silicon optoelectronic integration.Since silicon is one of the most widely used semiconductor materials today, Is used in large-scale integrated circuits. If the application of porous silicon light-emitting is achieved, it will have an immeasurable impact on the optoelectronics industry. Now, porous silicon has achieved red, green and blue emission, and electroluminescence has also been realized , Porous Silicon has taken a big step toward practicality.
